The Hole-in-the-Head  fiasco -- a nearly  complete breach of the reactor vessel closure head,  or lid -- was the  most infamous near-miss to a major reactor accident in  the U.S. since  the Three Mile Island meltdown in 1979. The Hole-in-the-Head fiasco added up to a boondoggle totaling more than $600 million.

Now it has been revealed that Davis-Besse has a hole in its Shield   Building wall -- an essential component of the radiological containment   structures -- that extends up to 12 inches through its 30-inch width, a   full 40% way through. Davis-Besse has operated for over two years, at   full power, with this potentially fatal flaw in its Shield Building   wall.
The gap or air space was discovered last Thursday, and publicly   revealed Friday, during the current Davis-Besse steam generator   replacement project, which has breached Davis-Besse's Shield Building   for an unprecedented fourth time. The previous three breaches include   the pre-operational Initial Construction Opening in the 1970s; the   2002-2004 reactor lid replacement project; and the 2011 reactor lid   replacement project. Each breach risks further damaging the Shield   Building, where severe cracking was discovered in late 2011. In   September 2013, FENOC admitted that the severe cracking is growing worse   over time.
NRC Region III Staff are holding a Webinar on Davis-Besse's current   steam generator replacement project on Thursday, Feb. 20th, from 6 to 7   PM Eastern. The Webinar was scheduled before revelation of the hole in   the containment wall. Please pre-register and attend the Webinar. Beyond Nuclear and Don't Waste MI have generated a series of sample questions you can put to NRC during the Webinar.
Beyond Nuclear helps lead environmental coalition efforts challenging   both the steam generator replacements, as well as FENOC's application   for a 20-year (2017-2037) license extension at Davis-Besse. Terry  Lodge,  Toledo-based attorney, serves as legal counsel for the  environmental  coalition in both NRC proceedings.
Arnie  Gundersen, Chief Engineer, Fairewinds Associates, Inc., serves  as  expert witness for the coalition in the "experimental" steam generator  replacement  intervention. Gundersen serves as expert witness for  Friends of the  Earth on the botched San Onofre 2 & 3 steam  generator replacements,  which has led to the permanent shutdown of  those two reactors -- a  multi-billion dollar boondoggle. Gundersen was  also instrumental in  outing the truth on the fatal cracking in Crystal  River, FL's concrete  containment, also caused by a botched steam  generator replacement,  another multi-billion dollar boondoggle. Gundersen has alleged that  Davis-Besse's steam generator replacement  has taken the same shortcuts  on safety, made all the worse by its  Shield Building's already very  questionable, and worsening, structural  integrity.
The coalition launched the challenge against the steam generator replacement in May, 2013, and defended its challenge in June and July -- twice in one month! -- 2013. The NRC Atomic Safety and Licensing Board (ASLB) which heard  the intervention quickly dismissed it, without addressing the merits,  effectively green-lighting Davis-Besse's shortcuts on safety. Beyond  Nuclear has posted the entire docket of the steam generator intervention on its website.
The Toledo Blade and Cleveland Plain Dealer have reported that the Davis-Besse steam generator replacements will cost $600 million.
Beyond Nuclear has filed a Freedom of Information Act Request on the gap in the Davis-Besse Shield Building wall.

NRC posted an Event Notification Report on Feb. 18, and a Preliminary Notification of Occurrence (PNO) on Feb. 19.

    Here are the questions that Beyond Nuclear's Kevin Kamps asked of the NRC Staff during the Webinar.
WKSU has reported on this story,   quoting an NRC official as saying: “It may be a bit premature to   speculate on where this ends up with  regard to license renewal, but   suffice it to say that we are evaluating  not only the number of times   the shield building has been cut, but also  the issues that have arisen   each time the shield building was cut.”
